Three ounces of cinnamon cost $2.40. If there are 16 ounces in 1 pound, how much does cinnamon cost per pound?

Answer 1

We know that 3 ounces of cinnamon costs $2.40.

1 ounce of cinnamon costs $0.80 (We divide $2.40 by 3).

Since there are 16 ounces in 1 pound, we multiply $0.80 by 16 ounces to find how much cinnamon costs per pound. The answer is $12.80.

Hope this helps!

Answer 2

1 pound means 16 ounces

Therefore one pound cinnamon means 16 ounces cinnamon

Hence,if 3 ounces cost =$2.40

So,16 ounces cost=($2.40*16)/3=$12.8

So,1 pound cinnamon cost=$12.8

Answer 3

Set up equivalent ratios:

(3 ounces) / $2.40 = (16 ounces) / x

Solve for x. (x is the cost for 16 ounces)

Answer 4

We need to convert dollars/ounces to dollars/pound:

$2.40 16 ounces

-------- * ------------- = $12.80/pound

3 ounces 1 pound
